` l Application tiled January 12, 1899. Serial 116.701.988. (No model.)

To @ZZ whom it may concern:

Be it known that I, DANIEL BARCKDALI., of Indianapolis, county ofMarion,.and State of Indiana, have invented a certain new and usefulGas-Making Apparatus; and I dovhereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, in which like figures refer to like parts.

he object of said invention is to simplify the construction of machinesof this character and to promote the better distribution of the airthrough the hydrocarbon.

In the drawings, Figure 1 is a central vertical section of the oil-tank.Fig. 2 is a plan of the rotary outlet-tube at the lower end of theairinlet tube. Fig. 3 is a section of the connection between saidoutlet-tube and the air-inlet tube. Fig. 4 is a diagram of my gas-Inaking apparatus.

In Fig. 4 the oil-tank lis shown with an oil supply or inlet pipe 2,regulated by a suitable valve. Entering said oil-tank there is anairinlet pipe 3, leading from the compressed-air tank and provided witha shut-0E valve 14 and a regulating-valve. There is also on the end nextto the compressed-air tank a pressure-gage to indicate the pressure ofthe air in the compressed-air tank. The air is cornpressed in said tankby a suitable pump of any desired construction calculated to compressthe air therein. The air-pipe 3 enters the tank centrally through itsupper end, as seen in Fig. 1, and is provided with the means thereinshown for distributing the air. The lower end of said pipe 3 isexternally threaded and on it I mount a spherical disk 4, that is heldin place by the nuts 5 and 6. Said disk is open at the bottom and itssurface is perforated throughout.

The lower end of the air-inlet pipe 3 is enlarged and perforated. Thisis eected, preferably, as shown, by securing the enlarged portion 8 tothe lower end of the main part of the pipe. .As shown, this part 8 is avessel with removable top and perforated sides. The bottom is closed,excepting the central aperture, through which the collared sleeve 9extends downward and fits loosely enough to be rotatable. To thiscollared sleeve I secure a T 10, and in it I secure theoppositely-extending air-tubes 11. In this way a passage-way is providedinto said tubes 11. These tubes 11 are S-shaped, being curved,substantially as shown, in opposite directions. The air is forcedthrough the pipe 3 with considerable force, and a portion of it escapesthrough the perforations at the lower end of the pipe and the remainder,about half, proceeds to pass out into the tank through the tubes 11. `Asthe air is forced through said tubes 411 because of their shape itcauses them to rotate, and in this manner the portion of air which goesthrough them is distributed as it comes out. When properly operated, thepressure of the incoming air is sufficient to keep the enlarged portion8 and the pipe 3, as well as the tubes 1l, entirely clear ot' oil. It isthus seen that as the air issues from the lower end of the pipe it isquite well distributed; but to further distribute it in the oil and tocause it to be scattered into minute particles or quantities the disk 4is so placed that substantially all such air will have to go through itsperforations. As the air-outletunder such disk is arranged with relationto the disk the air will be caused to pass through the various parts ofthe disk equably. After the air has escaped through the perforations ofsuch disk in minute quantities it continues to pass upward with greatforce through the body of the oil, and while passing out of the disk 4and through the body of the oil by reason of its comminution theparticles of air become carbureted. The gas thus is forced through theoutlet-pipe 12. It is preferable to collect the gas thus formed in areservoir or gas-tank, as shown in Fig. 4, and in such case the gaspipe12 would lead to said gas-tank, and from that tank the service-pipe 16extends to the burner. A mantle-burner is required for light on accountof the highly-volatile nature of the gas. For heating purposes anyordinary natural-gas burner may be used.

The service-pipe 16 is providedwith a suitable shutroff valve and alsowith a regulating-valve for regulating the pressure of the gas that goesto the burner, so that the pressure of the gas as it goes through theburner may be iiXed or modiiied regardless of the pressure of the gas inthe gas-tank or as it comes from the oiltank.

What I claim as my invention, and desire to secure by Letters Patent,is-

' 1. A gas-making apparatus including a hydrocarbon-tank, a mainair-pipe extending into the tank, an S-shaped outlet-pipe so.

mounted centrally at the lower end of the main air-pipe as to behorizontally rotatable by the pressure of air and having a passage-` Wayfrom such main air-pipe through it, and means for forcing air throughsaid main airpipe and the carburetor.

2. A gas -making apparatus including a tank, a main air-pipe centrallyextending into said tank, an enlarged potion or chamber at the lower endof said pipe With its sidesper-V forated, an S-shaped outlet-pipe somounted in the bottom of the enlarged portion or chamber as to behorizontally rotatable and have a passage from said chamber through it,and a perforated spherical disk so secured to the main pipe as tosurround and inclose the enlarged portion or chamber.

In Witness whereof Ihave hereunto affixed my signature in the presenceof the Witnesses herein named.

DANIEL BARCKDALL.
